Description

本発明は、化粧料を被塗布部に塗布するための化粧料容器に関する。   The present invention relates to a cosmetic container for applying a cosmetic to an application portion.

従来、容器内の例えば液状化粧料を始めとした流動性を有する化粧料を、流路を通じて塗布部へ送り塗布に供する化粧料容器にあっては、化粧料の一部が流動性の悪い化粧料になると、当該流動性の悪い化粧料により流路(吐出口を含む)が詰まってしまい、塗布に支障をきたす場合がある。   Conventionally, in a cosmetic container in which liquid cosmetics such as liquid cosmetics in a container are sent to an application part through a flow path for application, a part of the cosmetic has poor fluidity When the coating material is used, the flow channel (including the discharge port) may be clogged by the poorly fluid cosmetic material, which may hinder the application.

そこで、以下の特許文献1にあっては、例えば液状化粧料等の液体を射出する液体射出器において、ノズルに残留する液体を吸い戻すことで、残留液体の固化による目詰まりを防止する技術が開示されている。   Therefore, in Patent Document 1 below, for example, in a liquid ejector that injects liquid such as liquid cosmetics, there is a technique for preventing clogging due to solidification of the residual liquid by sucking back the liquid remaining in the nozzle. It is disclosed.

特許第4236748号公報Japanese Patent No. 4236748

しかしながら、上記特許文献1においては、液体が固化してしまった状態では、吸い戻すことができず、目詰まりが生じてしまう。   However, in the above-mentioned Patent Document 1, when the liquid is solidified, it cannot be sucked back and clogging occurs.

そこで、本発明は、流動性の悪い化粧料による詰まりを防止できると共に、流動性の良い化粧料による良好な塗布を可能とする化粧料容器を提供することを目的としている。   Therefore, an object of the present invention is to provide a cosmetic container that can prevent clogging due to cosmetics with poor fluidity and enables good application with cosmetics with good fluidity.

本発明による化粧料容器は、流動性を有する化粧料を収容可能な収容室を備える容器本体と、流動性を有する化粧料を塗布するための塗布部と、収容室の流動性を有する化粧料を塗布部へ導くための誘導筒と、を備え、誘導筒は、収容室に連通する開口部と、開口部から流入する流動性を有する化粧料を、当該誘導筒の軸線方向塗布部側に向かって流す流路と、流路の塗布部側を閉じ流れを堰き止める堰き止め部と、流路の堰き止め部より開口部側の位置に開口され、塗布部に連通する領域に繋がる誘導口と、を有することを特徴としている。   A cosmetic container according to the present invention includes a container body including a storage chamber capable of storing a fluid cosmetic, an application unit for applying the fluid cosmetic, and a fluid cosmetic of the storage chamber. A guide tube for guiding the liquid to the application unit, the guide tube having an opening communicating with the housing chamber and a fluid cosmetic flowing in from the opening on the side of the application unit in the axial direction of the guide tube. A flow channel that flows inward, a damming portion that closes the application portion of the flow channel and blocks the flow, and a guide port that opens to a position closer to the opening portion than the damming portion of the flow channel and leads to a region that communicates with the application portion It is characterized by having.

このような化粧料容器によれば、収容室の流動性を有する化粧料は、誘導筒の開口部を通して誘導筒内に流入し当該誘導筒内の流路を流れる。流動性の悪い化粧料は、誘導筒の流路の塗布部側を閉じた堰き止め部で堰き止められて溜められる。一方、流動性の良い化粧料は、堰き止め部に溜められている流動性の悪い化粧料から分離され、流路の堰き止め部より開口部側の位置に開口された誘導口に流入し、塗布部に連通する領域へと流れ、塗布部に送られる。このように、流動性の悪い化粧料を塗布部へ送ることを阻止でき、当該流動性の悪い化粧料による詰まりを防止できると共に、流動性の良い化粧料を塗布部へ送ることができ、当該流動性の良い化粧料による良好な塗布を行うことができる。   According to such a cosmetic container, the cosmetic material having fluidity in the storage chamber flows into the guide tube through the opening of the guide tube and flows through the flow path in the guide tube. Cosmetics with poor fluidity are dammed up and stored by a damming part that closes the application part side of the flow path of the guide tube. On the other hand, the cosmetics with good fluidity are separated from the cosmetics with poor fluidity stored in the damming part, and flow into the guide port opened to the position on the opening side from the damming part of the flow path, It flows to the area | region connected to an application part, and is sent to an application part. Thus, it is possible to prevent cosmetics with poor fluidity from being sent to the application part, prevent clogging with cosmetics with poor fluidity, and send cosmetics with good fluidity to the application part. Good application with a cosmetic material having good fluidity can be performed.

ここで、堰き止め部は、塗布部側にへこみ凹状に構成されると、当該堰き止め部に、流動性の悪い化粧料が好適に溜められる。   Here, when the damming portion is configured to have a concave shape on the application portion side, cosmetics having poor fluidity are suitably stored in the damming portion.

また、誘導口の大きさは、凹状の堰き止め部の開口より小さいと、誘導口と凹状の堰き止め部の開口の大きさの違いに従い、流動性の悪い化粧料は、選択的に堰き止め部に堰き止められ、流動性の良い化粧料は、選択的に誘導口に流入することになる。   In addition, if the size of the guide port is smaller than the opening of the concave damming portion, the cosmetic with poor fluidity is selectively dammed according to the difference in the size of the opening of the guide port and the concave damming portion. The cosmetics that are blocked by the part and have good fluidity selectively flow into the guide port.

また、誘導口を間に挟んだ堰き止め部と流路のうち、堰き止め部の誘導口側の内面位置は、流路の誘導口側の内面位置より径方向外側に位置していると、流動性の悪い化粧料は、誘導口に流入し難く、より好適に堰き止め部に堰き止められ、流動性の良い化粧料は、より好適に誘導口に流入し、このように、流動性の悪い化粧料と良い化粧料の分離性がより高められる。   Further, among the damming portion and the flow channel sandwiching the induction port therebetween, the inner surface position on the induction port side of the damming portion is located on the radially outer side from the inner surface position on the induction port side of the flow channel, Cosmetics with poor fluidity are unlikely to flow into the induction port, and are more preferably blocked by the damming unit, and cosmetics with good fluidity flow into the induction port more suitably, thus Separation between bad cosmetics and good cosmetics is further improved.

ここで、堰き止め部の内側に空気が溜まると、流動性の悪い化粧料が堰き止め部に溜まることが妨げられるようになる。そこで、堰き止め部は、その内側と、その外側に位置し塗布部に連通する領域とを繋ぐ空気孔を有しているのが好ましい。このような構成を採用した場合、堰き止め部の内側に溜まろうとする空気が、空気孔を通して、堰き止め部の外側に位置し塗布部に連通する領域に逃がされ、流動性が悪い化粧料を好適に堰き止め部に堰き止め溜めることができる。   Here, when air accumulates inside the damming portion, it is prevented that cosmetics having poor fluidity are accumulated in the damming portion. Therefore, it is preferable that the damming portion has an air hole that connects the inner side thereof and a region located on the outer side and communicating with the application portion. When such a structure is adopted, the air that is about to accumulate inside the damming part is released through the air holes to the area that is located outside the damming part and communicates with the application part, and has poor fluidity. Can be suitably stored in the damming portion.

このように本発明によれば、流動性の悪い化粧料による詰まりを防止できると共に、流動性の良い化粧料による良好な塗布を行うことができる。   As described above, according to the present invention, it is possible to prevent clogging due to cosmetics having poor fluidity, and it is possible to perform good application using cosmetics having good fluidity.

It is shown.

先ず、図1〜図9に示す第1実施形態を説明する。図1及び図2は、第1実施形態に係る化粧料容器の各外観図、図3及び図4は、図1及び図2の各断面図、図5は、先筒及び誘導筒を示す縦断面図、図6〜図9は、誘導筒を示す各図であり、本実施形態の化粧料容器は、流動性を有する化粧料を被塗布部に塗布する際に用いられるものである。流動性を有する化粧料としては、例えば、美容液、洗浄液、マスカラ、アンチエイジング、ネールケア溶液、頭髪用化粧料等の液状化粧料を始めとして、ジェル状や練り状等の流動性を有する化粧料を利用できる。   First, a first embodiment shown in FIGS. 1 to 9 will be described. 1 and 2 are external views of the cosmetic container according to the first embodiment, FIGS. 3 and 4 are cross-sectional views of FIGS. 1 and 2, and FIG. 5 is a longitudinal section showing a leading tube and a guide tube. FIG. 6 to FIG. 9 are each a diagram showing a guide tube, and the cosmetic container of this embodiment is used when applying a cosmetic material having fluidity to an application portion. Examples of fluid cosmetics include liquid cosmetics such as cosmetic liquids, cleaning liquids, mascara, anti-aging, nail care solutions, hair cosmetics, etc., and liquid cosmetics such as gels and kneads. Can be used.

図1〜図4に示すように、化粧料容器100は、流動性を有する化粧料を収容する収容室1aを備えた本体筒(容器本体)1と、本体筒1の後部に回転自在に連結された操作筒2と、本体筒1の先端部に連結された誘導筒3と、誘導筒3の先端側に連結され先端に塗布部4aを有する先筒4と、を外形構成として具備し、本体筒1に対して操作筒2を使用者が一方向(繰り出し方向)に回転すると、容器内に構成された押出機構としての螺合機構5及び回り止め機構6並びに一方向の回転を許容するラチェット機構7に従って、収容室1aに配設されたピストン8が本体筒1の先端側(塗布部4a側)に向かって順次繰り出され、収容室1aの流動性を有する化粧料を本体筒1の先端側に向かって順次押し出す構成とされている。なお、押出機構は、ラチェット機構がなく、ピストン8が前進/後退可能な構成であっても良い。また、本体筒1の先端部に着脱可能に装着され塗布部4aを覆うキャップは、ここでは、省略されている。   As shown in FIGS. 1 to 4, the cosmetic container 100 is rotatably connected to a main body cylinder (container main body) 1 including a storage chamber 1 a for storing cosmetics having fluidity and a rear portion of the main body cylinder 1. The outer cylinder includes an operation cylinder 2, a guide cylinder 3 connected to the distal end portion of the main body cylinder 1, and a front cylinder 4 connected to the distal end side of the guide cylinder 3 and having an application portion 4a at the distal end. When the user rotates the operation cylinder 2 in one direction (feeding direction) with respect to the main body cylinder 1, the screwing mechanism 5 and the anti-rotation mechanism 6 as an extrusion mechanism configured in the container and rotation in one direction are allowed. According to the ratchet mechanism 7, the piston 8 disposed in the storage chamber 1 a is sequentially drawn out toward the distal end side (applying portion 4 a side) of the main body cylinder 1, and cosmetics having fluidity in the storage chamber 1 a are supplied to the main body cylinder 1. It is set as the structure extruded sequentially toward the front end side. Note that the push-out mechanism may be configured such that the piston 8 can move forward / backward without the ratchet mechanism. Further, a cap that is detachably attached to the distal end portion of the main body cylinder 1 and covers the application portion 4a is omitted here.

次に、本体筒1の先端部に連結された本実施形態の特徴を成す誘導筒3並びに先筒4について説明する。   Next, the guide tube 3 and the front tube 4 that are the features of the present embodiment connected to the tip of the main body tube 1 will be described.

誘導筒3は、収容室1aの流動性を有する化粧料を先筒4の塗布部4aへ導くためのものであり、例えば、ポリエチレン、ポリプロピレン、その他のプラスチック材料より形成される。この誘導筒3は、本体筒1に装着されると共に先筒4を装着するホルダ部3aと、図6〜図9に示すように、ホルダ部3aに連設され先端側に向かって延びる誘導部3bと、を一体に備える。   The guide tube 3 is for guiding the cosmetic material having fluidity in the storage chamber 1a to the application part 4a of the front tube 4, and is formed of, for example, polyethylene, polypropylene, or other plastic materials. The guide tube 3 is attached to the main body tube 1 and the holder portion 3a to which the leading tube 4 is attached, and as shown in FIGS. 6 to 9, the guide portion is connected to the holder portion 3a and extends toward the distal end side. 3b.

ホルダ部3aは、略有底円筒状を呈し、後端部に鍔部3cを備える。この鍔部3cには、円環状の凹部3dが、本体筒1の先端部の円環状の凸部1dに軸線方向に係合するためのものとして設けられる。また、ホルダ部3aの鍔部3cより上方の外周面には、円筒の半周側に2個の突起3e,3eが、先筒4の凹部に進入し係合するためのものとして設けられる。この2個の突起3e,3eは、軸線を挟んだ反対側にも設けられる。ホルダ部3aの底部3fは、本体筒1の収容室1aの蓋となり、後端側が末広になるように先端側に向かって略擂り鉢状にへこむ形状を呈している。この略擂り鉢状の底部3fには、収容室1aに連通する開口部3gが開口されている。開口部3gはホルダ部3aの軸心を通り側面視くの字を呈すように一方向に延在する長孔であり(図7参照)、収容室1aの流動性を有する化粧料を誘導部3bに導くためのものである。   The holder portion 3a has a substantially bottomed cylindrical shape and includes a flange portion 3c at the rear end. The flange 3c is provided with an annular recess 3d for engaging with the annular projection 1d at the tip of the main body cylinder 1 in the axial direction. In addition, on the outer peripheral surface above the flange portion 3c of the holder portion 3a, two protrusions 3e and 3e are provided on the half circumference side of the cylinder so as to enter and engage with the concave portion of the front tube 4. The two protrusions 3e and 3e are also provided on the opposite side across the axis. The bottom portion 3f of the holder portion 3a serves as a lid of the storage chamber 1a of the main body cylinder 1, and has a shape that is recessed in a generally bowl shape toward the distal end side so that the rear end side becomes wider. An opening 3g communicating with the storage chamber 1a is opened in the substantially bowl-shaped bottom 3f. The opening portion 3g is a long hole extending in one direction so as to exhibit a cross-sectional shape passing through the axis of the holder portion 3a (see FIG. 7), and guides cosmetics having fluidity in the storage chamber 1a. It is for leading to 3b.

誘導部3bは、ホルダ部3aの先端側の面において開口部3g周りの位置に立設される。この誘導部3bは、扁平な略四角筒形状の長径側の端部を丸めた形状(以下扁平筒形状と呼ぶ)を呈し、その天部は閉じられている。そして、誘導部3bは、その扁平筒孔が、ホルダ部3aの長孔状の開口部3gに軸線方向に重なり連通するように設けられている。この誘導部3bの外周面とホルダ部3aの内周面は、誘導部3bの長径部分で繋がり一体とされる一方で(図3及び図6参照)、長径部分以外の部分にあっては、誘導部3bの外周面とホルダ部3aの内周面との間に、空間S1が形成されている(図4及び図6参照)。   The guide portion 3b is erected at a position around the opening 3g on the front end side surface of the holder portion 3a. The guiding portion 3b has a shape obtained by rounding the end portion on the long diameter side of a flat, substantially rectangular tube shape (hereinafter referred to as a flat tube shape), and its top portion is closed. And the guidance | induction part 3b is provided so that the flat cylindrical hole may overlap and communicate with the long hole-shaped opening part 3g of the holder part 3a in an axial direction. While the outer peripheral surface of the guide portion 3b and the inner peripheral surface of the holder portion 3a are connected and integrated with each other at the long diameter portion of the guide portion 3b (see FIGS. 3 and 6), A space S1 is formed between the outer peripheral surface of the guide portion 3b and the inner peripheral surface of the holder portion 3a (see FIGS. 4 and 6).

誘導部3bの扁平筒孔は、開口部3gから流入する流動性を有する化粧料を、誘導筒3の軸線方向先端側となる塗布部4a側に向かって流す流路3hを構成する。この流路3hを構成する誘導部3bの内面は、軸線方向途中から先端側に向かうに従い、その長径側が徐々に先細りとなる(対向する内面同士が接近していく)傾斜面とされ、その先端側である塗布部4a側は天部により閉じられている。そして、この天部を含む流路3hの先端側は、塗布部4a側にへこむ凹状を呈し、この凹状のへこみが、流動性を有する化粧料の流れを堰き止める堰き止め部3iとされる(詳しくは後述)。   The flat cylindrical hole of the guide portion 3b constitutes a flow path 3h that allows the flowable cosmetic material flowing in from the opening 3g to flow toward the application portion 4a side, which is the distal end side in the axial direction of the guide tube 3. The inner surface of the guiding portion 3b constituting the flow path 3h is an inclined surface whose long diameter side gradually tapers (the facing inner surfaces approach each other) as it goes from the middle in the axial direction toward the tip side, and its tip The application part 4a side which is the side is closed by the top part. And the front end side of the flow path 3h containing this top part presents the concave shape dented to the application part 4a side, and this concave shape becomes the damming part 3i which dams the flow of the cosmetics which have fluidity ( Details will be described later).

流路3hにおいて堰き止め部3iより開口部3g側の位置で、長径方向に離間する位置には、誘導部3bの軸線方向に直交する方向に向けて開口される誘導口3j,3jが対向するように設けられる。この誘導口3jは、流路3hの全幅(短径方向全体)に亘って設けられる(図9参照)。誘導口3jには、先端側へ向かう誘導路3kが連通し、この誘導路3kは、先端側に向かうに従い、長径側の開口が徐々に広がる傾斜口とされる。そして、この誘導路3kは、誘導部3bの天部を貫通し先筒4内と連通する。   In the flow path 3h, at the position on the opening 3g side of the damming portion 3i and spaced apart in the major axis direction, the guide ports 3j and 3j opened in the direction orthogonal to the axial direction of the guide portion 3b are opposed. It is provided as follows. The guide port 3j is provided over the entire width (the entire short axis direction) of the flow path 3h (see FIG. 9). The guide port 3j communicates with a guide path 3k toward the tip side, and the guide path 3k is an inclined port in which the opening on the long diameter side gradually widens toward the tip side. The guide path 3k passes through the top of the guide portion 3b and communicates with the inside of the front tube 4.

ここで、図8に示すように、誘導口3jの大きさは、凹状の堰き止め部3iの開口より小さくされている。また、ここでは、誘導口3jを間に挟んだ堰き止め部3iと流路3hのうち、堰き止め部3iの誘導口3j側の内面位置Pは、流路3hの誘導口3j側の内面位置Qより径方向内側に位置している。これは、誘導筒3の射出成形時において、先端側の金型で誘導路3kに対応する部分を有する金型と、後端側の金型で堰き止め部3iの内側部分(開口部3g側の部分)及び流路3hに対応する部分を有する金型を、それぞれ離れる方向に離型する際に、金型が無理抜きにならないようにするためである。そして、このような両金型の合わせ面(接触面)により成形される誘導口3jは、誘導部3bの軸線方向に直交する方向に向けて開口されたものとなる。   Here, as shown in FIG. 8, the size of the guide port 3j is made smaller than the opening of the concave damming portion 3i. Here, the inner surface position P on the guide port 3j side of the flow path 3h is the inner surface position on the guide port 3j side of the flow path 3h among the dam part 3i and the flow path 3h sandwiching the guide port 3j therebetween. It is located radially inward from Q. This is because, at the time of injection molding of the guide cylinder 3, a die having a portion corresponding to the guide path 3k on the tip side mold and an inner portion (on the opening 3g side) of the damming portion 3i on the back end side die. This is to prevent the mold from being forced out when the mold having the part corresponding to the part 3) and the part corresponding to the flow path 3h is released in the direction away from each other. And the induction | guidance | derivation opening 3j shape | molded by such a mating surface (contact surface) of both metal mold | dies will be opened toward the direction orthogonal to the axial direction of the guidance | induction part 3b.

先筒4は、例えば、エラストマー、シリコンゴム等の軟質弾性材より形成され、図4に示すように、外筒部4b及び内筒部4cを有する。外筒部4bは、その後部、具体的には、本体筒1の先端部に挿入される挿入部4dが円筒状に構成され、これより前側の外周面が、先端に行くに従い、図1及び図2に示すように、一方向(図2の上下方向)に長く、この一方向に直交する方向(図1の上下方向)に短い形状となるように、より具体的には、先筒4の先端が、略長方形形状の長径側の端部を丸めた形状となるように、徐々に狭まる構成とされる。挿入部4dの内周面には、誘導筒3のホルダ部3aの突起3eが進入し係合するための凹部が設けられている(図3及び図4においては断面から外れ隠れて見えない)。   The front tube 4 is made of, for example, a soft elastic material such as elastomer or silicon rubber, and has an outer tube portion 4b and an inner tube portion 4c as shown in FIG. The outer cylinder portion 4b has a rear portion, specifically, an insertion portion 4d inserted into the distal end portion of the main body cylinder 1, and is configured in a cylindrical shape. As shown in FIG. 2, more specifically, the front tube 4 has a shape that is long in one direction (vertical direction in FIG. 2) and short in a direction orthogonal to the one direction (vertical direction in FIG. 1). The tip of each of the two is gradually narrowed so as to have a shape obtained by rounding the end portion on the long diameter side of a substantially rectangular shape. On the inner peripheral surface of the insertion portion 4d, a recess is provided for the protrusion 3e of the holder portion 3a of the guide tube 3 to enter and engage (in FIG. 3 and FIG. 4, it is hidden from the cross section and cannot be seen). .

内筒部4cは、図3及び図4に示すように、扁平筒形状の誘導部3bを内挿する扁平筒形状を呈し先端側に延びている。この内筒部4cと外筒部4bは、図3に示すように、誘導部3bの長径部分では繋がり一体とされている一方で、長径部分以外の部分にあっては、図4に示すように、誘導筒3の空間S1に連通する空間S2が設けられている。空間S2は、先端側に延び、外筒部4bと内筒部4cが合流する先端部で閉じられている。この空間S2は、先筒4の肉厚の均一化を図ることで、射出成形時の肉ひけ(ボイドを含む)の発生を防止するためのものである。   As shown in FIGS. 3 and 4, the inner cylinder portion 4 c has a flat cylindrical shape for inserting the flat cylindrical guide portion 3 b and extends to the distal end side. As shown in FIG. 3, the inner cylinder portion 4 c and the outer cylinder portion 4 b are connected and integrated at the long diameter portion of the guide portion 3 b, while the portions other than the long diameter portion are shown in FIG. 4. In addition, a space S2 communicating with the space S1 of the guide tube 3 is provided. The space S2 extends to the distal end side and is closed at the distal end where the outer cylindrical portion 4b and the inner cylindrical portion 4c merge. This space S2 is intended to prevent the occurrence of sink marks (including voids) during injection molding by making the thickness of the front tube 4 uniform.

内筒部4cの扁平筒孔は、図3に示すように、誘導筒3の流路3h、誘導口3j、誘導路3kを介して流出してくる流動性を有する化粧料を、軸線方向塗布部4a側に向かって流し塗布部4aへ導くための流路4eを構成する。すなわち、流路4eは、塗布部4aに連通する領域を構成し、この領域に対して、誘導筒3の誘導口3jが繋がる構成とされている。   As shown in FIG. 3, the flat cylindrical hole of the inner cylinder portion 4 c is coated with a cosmetic material having fluidity flowing out through the flow path 3 h, the guide port 3 j, and the guide path 3 k of the guide cylinder 3 in the axial direction. The flow path 4e for flowing toward the part 4a side and leading to the application part 4a is configured. That is, the flow path 4e constitutes a region communicating with the application part 4a, and the guide port 3j of the guide tube 3 is connected to this region.

そして、外筒部4bと内筒部4cが合流した先筒4の先端部には、流路4eに軸線方向に重なるように連通し当該流路4eと同形状の扁平形状の吐出口4fが開口される。この扁平形状の吐出口4fの周囲には、突起群4hが先筒4と一体に設けられ、これら吐出口4f及び突起群4hにより塗布部4aが構成される。   A flat discharge port 4f having the same shape as that of the flow path 4e communicates with the flow path 4e so as to overlap the flow path 4e at the distal end portion of the front cylinder 4 where the outer cylinder portion 4b and the inner cylinder portion 4c merge. Opened. Around the flat discharge port 4f, a projection group 4h is provided integrally with the front tube 4, and the discharge port 4f and the projection group 4h constitute an application portion 4a.

なお、塗布部4aを構成するのは、突起群に限定されるものではなく、例えばブラシ等でも良く、さらには、突起群やブラシ等がなく、吐出口のみを有する単なる塗布面であっても良い。   The application portion 4a is not limited to the projection group, and may be, for example, a brush or the like. Furthermore, the application unit 4a may be a simple application surface having only the discharge port without the projection group and the brush. good.

そして、図5に示すように、先筒4は誘導筒3に外挿され、その挿入部4dの後端面が、誘導筒3の鍔部3cの先端面に突き当たり、先筒4の凹部に誘導筒3のホルダ部3aの突起3e(図6及び図7参照)が進入し係合することで、誘導筒3に回転不能且つ軸線方向移動不能に装着され、一体とされる。   Then, as shown in FIG. 5, the front tube 4 is extrapolated to the guide tube 3, and the rear end surface of the insertion portion 4 d hits the front end surface of the flange portion 3 c of the guide tube 3 and is guided to the recess of the front tube 4. When the protrusion 3e (see FIGS. 6 and 7) of the holder portion 3a of the tube 3 enters and engages, the guide tube 3 is mounted so as not to rotate and to move in the axial direction, and is integrated.

このようにして一体とされた先筒4及び誘導筒3は、図3及び図4に示すように、本体筒1に内挿され、先筒4の段部4gが本体筒1の先端面に突き当てられ、誘導筒3の凹部3dが本体筒1の凸部1dに軸線方向に係合することで、本体筒1に軸線方向移動不能に装着される。   As shown in FIGS. 3 and 4, the front tube 4 and the guide tube 3 integrated as described above are inserted into the main body tube 1, and the step portion 4 g of the front tube 4 is placed on the front end surface of the main body tube 1. The concave portion 3d of the guide tube 3 is engaged with the convex portion 1d of the main body tube 1 in the axial direction so that the main body tube 1 is mounted so as not to move in the axial direction.

このように構成された化粧料容器100によれば、使用者による本体筒1と操作筒2との回転操作に従ってピストン8が前進し収容室1aから流動性を有する化粧料が押し出され、この化粧料は、誘導筒3の開口部3gを通して誘導筒3内に流入し流路3hを流れる。   According to the cosmetic container 100 configured in this way, the piston 8 moves forward in accordance with the rotation operation of the main body cylinder 1 and the operation cylinder 2 by the user, and the cosmetic having fluidity is pushed out from the storage chamber 1a. The charge flows into the guide tube 3 through the opening 3g of the guide tube 3 and flows through the flow path 3h.

ここで、流動性を有する化粧料の一部が流動性の悪い化粧料になると、誘導口3jより塗布部4a側に位置する堰き止め部3iで堰き止められて溜められる。一方、流動性の良い化粧料は、堰き止め部3iに溜められている流動性の悪い化粧料から分離されて誘導口3jに流入し、誘導路3kを流れて先筒4内に流出する。流出した流動性の良い化粧料は、先筒4の流路4eを流れて吐出口4fから吐出し、突起群4hによる塗布に供される。   Here, when a part of cosmetics having fluidity becomes cosmetics with poor fluidity, they are dammed up and stored by a damming part 3i located on the application part 4a side from the guide port 3j. On the other hand, cosmetics with good fluidity are separated from cosmetics with poor fluidity stored in the damming portion 3i, flow into the guide port 3j, flow through the guide path 3k, and flow into the front tube 4. The flowable cosmetic material that has flowed out flows through the flow path 4e of the front tube 4, discharges from the discharge port 4f, and is applied to the protrusion group 4h.

このように、本実施形態においては、堰き止め部3iにより、流動性の悪い化粧料を塗布部4aへ送ることを阻止でき、当該流動性の悪い化粧料による詰まりを防止できると共に、流動性の良い化粧料を塗布部4aへ送ることができ、当該流動性の良い化粧料による良好な塗布を行うことができる。   As described above, in the present embodiment, the blocking unit 3i can prevent the poorly fluid cosmetic from being sent to the application unit 4a, can prevent clogging by the poorly fluid cosmetic, and can prevent fluidity. Good cosmetics can be sent to the application part 4a, and the good application | coating with the said fluid good cosmetics can be performed.

また、本実施形態においては、堰き止め部3iは、塗布部4a側にへこみ凹状に構成されるため、当該堰き止め部3iに、流動性の悪い化粧料を好適に溜めることができる。   Moreover, in this embodiment, since the damming part 3i is comprised by the application part 4a side and is dented, it can accumulate | store the cosmetics with bad fluidity | liquidity in the said damming part 3i suitably.

また、誘導口3jの大きさは、凹状の堰き止め部3iの開口より小さいため、誘導口3jと凹状の堰き止め部3iの開口の大きさの違いに従い、流動性の悪い化粧料を、選択的に堰き止め部3iに堰き止めることができ、流動性の良い化粧料を、選択的に誘導口3jに流入させることができる。   Further, since the size of the guide port 3j is smaller than the opening of the concave damming portion 3i, a cosmetic with poor fluidity is selected according to the difference in the size of the opening of the guide port 3j and the concave damming portion 3i. Thus, the damming portion 3i can be dammed, and the cosmetic material having good fluidity can be selectively introduced into the guide port 3j.

図10は、本発明の第2実施形態に係る化粧料容器の先筒及び誘導筒を示す縦断面図である。なお、この第2実施形態を含む以降の実施形態においては、他の実施形態と同一の要素又は同一の機能を果たすものには同一の符号を付し、重複する説明は省略する。   FIG. 10 is a longitudinal sectional view showing a leading tube and a guide tube of a cosmetic container according to the second embodiment of the present invention. In the following embodiments including the second embodiment, the same elements or the same functions as those of the other embodiments are denoted by the same reference numerals, and redundant description is omitted.

この第2実施形態が第1実施形態と違う点は、誘導筒3に代えて、誘導部3bの流路3hを先端側に延ばし、堰き止め部3iが先筒4の流路4eに突出する誘導筒13を用いた点である。   The second embodiment is different from the first embodiment in that instead of the guide tube 3, the flow path 3 h of the guide portion 3 b is extended to the tip side, and the damming portion 3 i protrudes into the flow path 4 e of the front tube 4. This is a point using the guide tube 13.

この誘導筒13にあっては、誘導口3jが、先筒4の流路4eに突出している部分に開口されている。そして、このように、誘導口3jが、先筒4の流路4eに突出している部分に開口されているため、先筒4の流路4eに直接繋がる構成とされている。   In the guide tube 13, the guide port 3 j is opened at a portion protruding into the flow path 4 e of the front tube 4. In this manner, the guide port 3j is opened at a portion protruding into the flow path 4e of the front tube 4, and thus is configured to be directly connected to the flow path 4e of the front tube 4.

このような第2実施形態においても、第1実施形態とほぼ同様な効果を得ることができるのに加えて、第1実施形態の誘導路3kを不要にできるという利点がある。なお、誘導筒13は、先端側の金型で堰き止め部3iの外側部分(塗布部4a側の部分)に対応する部分を有する金型、及び、後端側の金型で堰き止め部3iの内側部分及び流路3hに対応する部分を有する金型を用いて成形され、誘導口3jは、軸線方向に直交する方向に短尺に延びるピン状の金型を別途用いることにより成形される。   Such a second embodiment also has the advantage that the guiding path 3k of the first embodiment can be dispensed with in addition to obtaining substantially the same effect as the first embodiment. In addition, the guide cylinder 13 is a die having a portion corresponding to an outer portion of the damming portion 3i (a portion on the application portion 4a side) on the tip side, and a damming portion 3i on the rear end side die. The guide port 3j is molded by separately using a pin-shaped mold that extends in a direction perpendicular to the axial direction.

図11は、本発明の第3実施形態に係る化粧料容器の先筒及び誘導筒を示す縦断面図である。   FIG. 11 is a longitudinal sectional view showing a leading tube and a guide tube of a cosmetic container according to the third embodiment of the present invention.

この第3実施形態が第1実施形態と違う点は、誘導筒3に代えて、別の誘導路14kを有すると共に第1実施形態の誘導路3kがない誘導筒14を用いた点である。   The third embodiment differs from the first embodiment in that instead of the guide tube 3, a guide tube 14 having another guide path 14k and having no guide path 3k of the first embodiment is used.

誘導路14kは、第1誘導路14mと第2誘導路14nを有する。   The guide path 14k includes a first guide path 14m and a second guide path 14n.

第1誘導路14mは、誘導口3jに連通すると共に軸線方向に直交する方向に向かって延び誘導部3bの外周面に開口される。   The first guide path 14m communicates with the guide port 3j and extends in a direction orthogonal to the axial direction and is opened on the outer peripheral surface of the guide portion 3b.

第2誘導路14nは、誘導部3bの外周面に凹設されて軸線方向に延在しその一端が第1誘導路14mに連通すると共に、その他端が流路4eに開口される溝14pを設けることで、当該溝14pとこの溝14pに対面する先筒4の内周面との間に形成される。溝14pは、ここでは、例えば矩形断面又は略半円断面等の断面形状を有する溝とされる。   The second guide path 14n is recessed in the outer peripheral surface of the guide portion 3b and extends in the axial direction. One end of the second guide path 14n communicates with the first guide path 14m, and the other end has a groove 14p opened in the flow path 4e. By providing, it forms between the said groove | channel 14p and the internal peripheral surface of the front cylinder 4 which faces this groove | channel 14p. Here, the groove 14p is a groove having a cross-sectional shape such as a rectangular cross section or a substantially semicircular cross section.

このような第3実施形態においても、流動性の悪い化粧料は、堰き止め部3iで堰き止められ、流動性の良い化粧料は、誘導口3j、誘導路14kを通り流路4eに流入して、塗布部4aへ送ることができ、第1実施形態とほぼ同様な効果を得ることができる。なお、誘導筒14は、先端側の金型で溝14pに対応する部分を有する金型、及び、後端側の金型で堰き止め部3iの内側部分及び流路3hに対応する部分を有する金型を用いて成形され、誘導口3j及び第1誘導路14mは、軸線方向に直交する方向に長尺に延びるピン状の金型を別途用いることにより成形される。   Also in the third embodiment, cosmetics with poor fluidity are blocked by the blocking unit 3i, and cosmetics with good fluidity flow into the flow path 4e through the guide port 3j and the guide path 14k. Thus, it can be sent to the application unit 4a, and the same effect as in the first embodiment can be obtained. The guide cylinder 14 has a die having a portion corresponding to the groove 14p on the front end side mold, and a portion corresponding to the inner portion of the damming portion 3i and the flow path 3h on the rear end side die. The guide port 3j and the first guide path 14m are formed by separately using a pin-shaped mold that extends long in a direction orthogonal to the axial direction.

図12は、本発明の第4実施形態に係る化粧料容器の先筒及び誘導筒を示す縦断面図である。   FIG. 12 is a longitudinal sectional view showing a leading tube and a guide tube of a cosmetic container according to the fourth embodiment of the present invention.

この第4実施形態が第3実施形態と違う点は、誘導筒14に代えて、溝14pがない誘導筒15を用いると共に、先筒4に代えて、溝14pを誘導筒14から移し替えた先筒24を用いた点である。   The fourth embodiment is different from the third embodiment in that a guide tube 15 having no groove 14p is used instead of the guide tube 14, and the groove 14p is moved from the guide tube 14 instead of the front tube 4. The point is that the front tube 24 is used.

ここで、先筒24の溝14pは、その一端が第1誘導路14mに連通し、その他端が流路4eに開口される構成とされ、この溝14pと当該溝14pに対面する誘導筒15の誘導部3bの外周面との間に、第2誘導路24nが形成される。そして、第1誘導路14mと第2誘導路24nにより、誘導路24kが構成される。   Here, the groove 14p of the front tube 24 is configured such that one end thereof communicates with the first guide path 14m and the other end is opened to the flow path 4e, and the guide tube 15 facing the groove 14p and the groove 14p. A second guide path 24n is formed between the guide section 3b and the outer peripheral surface of the guide section 3b. The first guide path 14m and the second guide path 24n constitute a guide path 24k.

このような第4実施形態においても、流動性の悪い化粧料は、堰き止め部3iで堰き止められ、流動性の良い化粧料は、誘導口3j、誘導路24kを通り流路4eに流入して、塗布部4aへ送ることができ、第3実施形態とほぼ同様な効果を得ることができる。なお、誘導筒15は、先端側の金型、及び、後端側の金型で堰き止め部3iの内側部分及び流路3hに対応する部分を有する金型を用いて成形され、誘導口3j及び第1誘導路14mは、軸線方向に直交する方向に長尺に延びるピン状の金型を別途用いることにより成形される。   Also in the fourth embodiment, cosmetics with poor fluidity are blocked by the blocking unit 3i, and cosmetics with good fluidity flow into the flow path 4e through the guide port 3j and the guide path 24k. Thus, it can be sent to the application part 4a, and the same effect as in the third embodiment can be obtained. The guide cylinder 15 is formed by using a die having a tip side die and a die having a rear end side die and an inner portion of the damming portion 3i and a portion corresponding to the flow path 3h. The first guide path 14m is formed by separately using a pin-shaped mold extending long in a direction orthogonal to the axial direction.

図13は、本発明の第5実施形態に係る化粧料容器の先筒及び誘導筒を示す縦断面図である。   FIG. 13 is a longitudinal sectional view showing a leading tube and a guide tube of a cosmetic container according to a fifth embodiment of the present invention.

この第5実施形態が第1実施形態と違う点は、誘導筒3に代えて、堰き止め部16iをさらに有する誘導筒16を用いた点である。   The fifth embodiment is different from the first embodiment in that a guide cylinder 16 further having a damming portion 16i is used instead of the guide cylinder 3.

この誘導筒16にあっては、流路3hを構成する誘導部3bの内面(正確には誘導口3jより開口部3g側の内面)を先端側に折り曲げることで、誘導路3kより外側の位置、すなわち堰き止め部3iの両側方に、凹状の堰き止め部16i,16iが設けられている。   In this guide cylinder 16, the inner surface of the guide portion 3b constituting the flow path 3h (more precisely, the inner surface on the opening portion 3g side of the guide port 3j) is bent toward the tip side, so that the position outside the guide path 3k. That is, concave damming portions 16i, 16i are provided on both sides of the damming portion 3i.

このような第5実施形態においても、第1実施形態とほぼ同様な効果を得ることができるのに加えて、堰き止め部16i,16iにおいても流動性の悪い化粧料を堰き止め溜めることができるため、流動性の悪い化粧料による詰まりを一層防止できると共に、流動性の良い化粧料による一層良好な塗布を行うことができる。なお、誘導筒16は、先端側の金型で誘導路3kに対応する部分を有する金型と、後端側の金型で堰き止め部3iの内側部分及び流路3hに対応する部分を有する金型を用い、両金型をそれぞれ離れる方向に離型することで成形できる。   In the fifth embodiment as well, in addition to being able to obtain substantially the same effect as in the first embodiment, it is possible to dam up and store cosmetics having poor fluidity in the damming portions 16i and 16i. Therefore, it is possible to further prevent clogging due to cosmetics with poor fluidity and to perform better application with cosmetics with good fluidity. The guide cylinder 16 has a die having a portion corresponding to the guide path 3k in the tip side mold, and a portion corresponding to the inner portion of the damming portion 3i and the flow path 3h in the rear end side die. Molding can be performed by using a mold and releasing both molds in directions away from each other.

ここで、上記第1、第5実施形態においては、前述したように、成形時に先端側及び後端側の金型のみを用いて無理抜きしないようにしている。具体的な構成としては、誘導口3jを間に挟んだ堰き止め部3iと流路3hのうち、堰き止め部3iの誘導口3j側の内面位置Pを、流路3hの誘導口3j側の内面位置Qより径方向内側に位置するようにしているが、次の第6実施形態においては、金型を無理抜きすることなく、堰き止め部3iの誘導口3j側の内面位置Pを、流路3hの誘導口3j側の内面位置Qより径方向外側に位置するようにしている。   Here, in the first and fifth embodiments, as described above, only the front end side and rear end side molds are used during molding so as not to be forcibly removed. As a specific configuration, the inner surface position P on the guide port 3j side of the damming portion 3i of the damming portion 3i and the flow channel 3h sandwiching the guide port 3j therebetween is set on the guide port 3j side of the flow channel 3h. In the sixth embodiment, the inner surface position P on the guide port 3j side of the damming portion 3i is flowed without forcibly removing the mold in the sixth embodiment. The path 3h is positioned radially outward from the inner surface position Q on the guide port 3j side.

図14は、本発明の第6実施形態に係る化粧料容器の誘導筒を斜め上方から見た斜視図、図15は、図14に示す誘導筒の縦断面図、図16は、図15に直交する方向の縦断面図である。   14 is a perspective view of the guide tube of the cosmetic container according to the sixth embodiment of the present invention as seen obliquely from above, FIG. 15 is a longitudinal sectional view of the guide tube shown in FIG. 14, and FIG. It is a longitudinal cross-sectional view of the orthogonal direction.

この第6実施形態が第1実施形態と違う点は、誘導筒3を、2分割の誘導筒17に代えた点である。   The sixth embodiment is different from the first embodiment in that the guide tube 3 is replaced with a two-part guide tube 17.

誘導筒17は、その誘導部3bが、堰き止め部3iを含む天部を備えた有天扁平筒形状の蓋部17aと、これより開口部3g側の部分、具体的には、流路3h、誘導口3j及び誘導路3k等を含む扁平筒形状部分17bとに分割され、この扁平筒形状部分17bに蓋部17aが被さる構成とされている。   The guide tube 17 includes a lid portion 17a having a ceiling-like flat tube shape in which the guide portion 3b includes a top portion including a damming portion 3i, and a portion closer to the opening 3g, specifically, a flow path 3h. The flat cylindrical portion 17b including the guide port 3j, the guide path 3k, and the like is divided, and the flat cylindrical portion 17b covers the lid portion 17a.

蓋部17aには、扁平筒形状部分17bの誘導路3kに軸線方向に重ねるように連通する導出口17kが開口される。   The lid portion 17a has an outlet port 17k that communicates with the guide path 3k of the flat cylindrical portion 17b so as to overlap in the axial direction.

扁平筒形状部分17bにあっては、流路3hの誘導口3j側の部分が、誘導口3jより扁平筒形状部分17bの軸心に向かって突出する突出部3rとされている。この突出部3rは、その先端がさらに先端側に向かうように折曲されている。このように、第6実施形態においては、堰き止め部3iの誘導口3j側の内面位置Pが、流路3hの誘導口3j側の内面位置Qより径方向外側に位置している。そして、扁平筒形状部分17bに蓋部17aを被せることにより、蓋部17aの堰き止め部3iの端部と扁平筒形状部分17bの突出部3rとの間に、誘導口3jが形成される。   In the flat cylindrical portion 17b, the portion on the guide port 3j side of the flow path 3h is a protruding portion 3r that protrudes from the guide port 3j toward the axis of the flat cylindrical portion 17b. The protrusion 3r is bent so that the tip is further toward the tip. Thus, in the sixth embodiment, the inner surface position P on the guide port 3j side of the damming portion 3i is located on the radially outer side from the inner surface position Q on the guide port 3j side of the flow path 3h. Then, by covering the flat cylindrical portion 17b with the lid portion 17a, the guide port 3j is formed between the end portion of the damming portion 3i of the lid portion 17a and the protruding portion 3r of the flat cylindrical portion 17b.

このような第6実施形態においても、第1実施形態とほぼ同様な効果を得ることができるのに加えて、堰き止め部3iの誘導口3j側の内面位置Pが、流路3hの誘導口3j側の内面位置Qより径方向外側に位置しているため、流動性の悪い化粧料は、誘導口3jに流入し難く、より好適に堰き止め部3iで堰き止めることができると共に、流動性の良い化粧料は、より好適に誘導口3jに流入させることができ、その結果、流動性の悪い化粧料と良い化粧料の分離性をより高めることができる。加えて、この実施形態では、突出部3rの先端が、先端側に向かうように折曲されているため、流動性の悪い化粧料は誘導口3jに一層流入し難く、流動性の悪い化粧料と良い化粧料の分離性をより一層高めることができる。   In the sixth embodiment as well, in addition to being able to obtain substantially the same effect as the first embodiment, the inner surface position P on the guide port 3j side of the damming portion 3i is the guide port of the flow path 3h. Since it is located radially outward from the inner surface position Q on the 3j side, cosmetics with poor fluidity are unlikely to flow into the guide port 3j, and can be more suitably dammed by the damming portion 3i, and also have fluidity. The cosmetics with good quality can be flowed into the guide port 3j more suitably, and as a result, the separability between the cosmetics with poor fluidity and the good cosmetics can be further enhanced. In addition, in this embodiment, since the tip of the protruding portion 3r is bent toward the tip side, the cosmetic material with poor fluidity is less likely to flow into the guide port 3j, and the cosmetic material with poor fluidity is used. And the separation of good cosmetics can be further enhanced.

また、上記P,Qの位置関係にあっても、誘導筒17の誘導部3bは、蓋部17aと扁平筒形状部分17bに2分割されているため、離型の際に、金型が無理抜きにならないようになっている。   Even in the positional relationship of P and Q, the guide part 3b of the guide cylinder 17 is divided into two parts, a lid part 17a and a flat cylindrical part 17b. It is designed not to skip.

図17は、本発明の第7実施形態に係る化粧料容器の誘導筒を斜め上方から見た斜視図、図18は、図17に示す誘導筒の縦断面図である。   FIG. 17 is a perspective view of the guide tube of the cosmetic container according to the seventh embodiment of the present invention as viewed obliquely from above, and FIG. 18 is a longitudinal sectional view of the guide tube shown in FIG.

この第7実施形態が第1実施形態と違う点は、堰き止め部3iに、その内側(開口部3g側)と、その外側(塗布部4a側)に位置し塗布部4aに連通する領域である流路4eとを繋ぐ空気孔3tを設けた点である。   The seventh embodiment is different from the first embodiment in that the damming portion 3i is located on the inner side (opening portion 3g side) and on the outer side (application portion 4a side) and communicates with the application portion 4a. This is the point that an air hole 3t that connects a certain flow path 4e is provided.

ここで、空気孔3tは小径の空気孔であり、当該空気孔3tを通して流動性の悪い化粧料が通過しない大きさに設定されている。   Here, the air hole 3t is a small-diameter air hole, and is set to a size that prevents cosmetics having poor fluidity from passing through the air hole 3t.

このような第7実施形態においても、第1実施形態とほぼ同様な効果を得ることができるのに加えて、堰き止め部3iの内側に溜まろうとする空気が、空気孔3tを通して、流路4eに逃がされ、流動性が悪い化粧料を好適に堰き止め部3iに堰き止め溜めることができる。   In the seventh embodiment as well, in addition to being able to obtain substantially the same effect as in the first embodiment, air trying to accumulate inside the damming portion 3i passes through the air hole 3t and flows into the flow path 4e. Therefore, cosmetics that are released and are poorly fluid can be suitably stored in the damming portion 3i.

なお、この空気孔3tは、第2〜第6実施形態の堰き止め部3iに対しても適用可能である。   In addition, this air hole 3t is applicable also to the blocking part 3i of 2nd-6th embodiment.
